Dear Ma'am/Sir, 
I hope this message finds you well. My name is Clarisse De Villa, a 4th year Civil Engineering Student from Technological Institute of the Philippines - Quezon City, and I am reaching out to request data regarding sedimentation yield in the Maasin Watershed or Maasin area of Iloilo. As part of our Capstone Project entitled "Design of Sediment Control Infrastructure for Maasin Watershed in Maasin Iloilo", we are keen on obtaining accurate information regarding sedimentation in the region.

Specifically, we are interested in data encompassing the past 10 to 15 years to analyze trends and patterns in sedimentation accumulation.

Could you kindly provide us with the following details:
1. Sedimentation yield data (preferably in tabular format) for the specified time period.

Thank you very much for your attention to this matter.
